Abstract
GeO2-coated MCMB was prepared by chemical reduction method. The structure and morphology of the material were characterized by X ray diffraction (XRD) and scanning electron microscopy (SEM). Cyclic Voltammetry and galvanostatic charge/discharge tests were carried out to measure electrochemical performance. The composites exhibited a stability in a PC-based electrolyte which can suppress the decomposition of propylene carbonate and the exfoliation of graphite layer, compared with bare MCMB electrode. GeO2-coated MCMB electrode is expected to have good performance at low temperature.
